Tension of the cord

  1. Apr 24, 2009 #1
    1. The problem statement, all variables and given/known data
    Two blocks of mass m1 = 4.50 kg and m2 = 7.50 kg are connected by a massless string that passes over a frictionless pulley.The inclines are frictionless.

    p4-54alt.gif


    the magnitude of acceleration of each block is 1.4 m/s^2


    Find the tension in the string.
    ?_?
    may someone help me start this problem

    Start by drawing a free-body diagram for each block.
    Identify the forces and directions of each force on blocks 1 and 2 separately.
    Then do you know how to find the tension?

    yeah i tried that. thanks
    i figured out the problem

    sum of the force = Tension- M G sin 35 = M A
